Having never owned a black, I can't speak to their personalities. I have thoroughly enjoyed raising my silvers though.
The first was likely my favorite. Got very large, VERY quickly and was essentially hand fed every night. I lost him when he jumped.
The second was a rescue who I watched go from broken, fin-less mess to a beautiful 18" beast with gorgeous coloring. I gave him to a friend with a larger tank than my 180.
This third one I purchased when he was 2" long. He's now well over a foot and developing a personality. He will accept food from my hand, but he's just as likely to try and bite a finger.
Bottom line, I've always loved my Silvers - despite their droopy eyes and occasional psychopathic behavior, they are among my favorite fish to keep. I'm sure you won't be upset if you decide to go the silver route.
